Reactivity of Cp*M (M = Co, Rh, Ir) half-sandwich complexes containing a chelating 1,2-dicarba-closo-dodecaborane-1,2-dichalcogenolato ligand with organic azides

摘要

The reactivity of unsaturated 16-electron half-sandwich complexes Cp*M(S2C2B10H10) (Cp* is pentamethylcyclopentadienyl, M = Co, Rh, Ir) towards various organic azides was studied. The difference in the metal center and organic azides led to products with different coordination modes, which were characterized by H-1, B-11, and C-13 NMR spectroscopy, IR spectroscopy, elemental analysis, and X-ray diffraction.
